Abstract
In the present paper, areas under risk of floods are identified on the basis of the
codified return periods of flood events, and appropriate river strips are then
identified, with reference to which the actions of territorial planning and risk
mitigation works can be defined. Hydraulic risk is determined by evaluating
the expected damage to vulnerable elements (first and foremost anthropic
elements) resulting from the occurrence of an event of known dangerousness.
Therefore the level of risk derives from the estimate of phenomenon
dangerousness (linked to the identification of the relative river strips with
assigned return period) and from the vulnerability of the exposed elements.
The risk is determined by means of matrixes that, even if characterized by
intrinsic limitations, make it fairly straightforward to estimate a small number
of parameters and hence evaluate risk level and attention level in flood
phenomena for single hydrographical networks.
Keywords: flood event, hydraulic risk, mathematical model analysis, risk
matrixes.
1 Introduction
With every passing year, the scientific community observes ongoing climate
change which has, among other things, modified the values of extreme
hydrological events. Demographic increase combined with rising land prices due
to the shortage of building areas, has led to a disordered and indiscriminate land
use with all kinds of installations being built in areas at high risk of flooding.
In conjunction with scarce monitoring and maintenance of the territory,
modification of drainage networks, deforestation and topographical changes,
Keywords
flood event, hydraulic risk, mathematical model analysis, risk
matrixes.
